炭疽病是葡萄上的重要病害之一,因主要为害果实,对产量影响很大。日本曾对该病进行过研究,他们认为:结果母枝(即植株上的一年生枝)是翌年的初次侵染源,其他国家尚未见研究报道。我国有关文献、书籍上记载:病果是翌年的初次侵染源,并一直按传统的方法防治,因此收效不大,常常造成丰年不丰收的严重局面。鉴于以上情况,笔者自1979年以来,对此病的发生规律、病原菌的生物学特性及其防 Anthracnose is one of the most important diseases on grapes. It mainly affects the fruits and has a great influence on the yield. Japan has studied the disease, they believe: the result of mother (that is, annual branch of the plant) is the first year of the source of infection, no other countries have been reported. According to our relevant documents and books, sick fruit is the primary source of infection in the following year and has been controlled according to the traditional methods. As a result, it has little effect and often leads to a serious situation in which the harvest of New Year is not abundant. In view of the above, the author since 1979, the occurrence of the disease, the biological characteristics of pathogens and their prevention
